My marker has a light weight, ridged metal, narrow flat base 15, with anairfoam pad 1 6 on top at this narrow end of base 15. FIG. 1, on base 15still flat but wider is 17. About 95 of the distance from the beginningis a back plate 18, with of the wider base 19 running past plate 18.FIG. 4.

The back plate 18 has an opening 20 through the center of the lower partof plate 18, FIG. 2, on the front of the back plate 18 along bothvertical sides of opening 20, from the top of the back plate 18, to thebase 17, are 2 front braces 21 and 2 2, a separate cover 23 and 24 isover the top of braces 21 to 22, covers 23 and 24 extend to each side ofplate 18 and to be even with outer edge area of base 17 FIG. 2, a rimdrops down along the edge of outer sides of the covers 23 and 24,starting from the back plate 18 and around to the front braces 21 and 22FIG. 2.

Above the opening in plate 18, between the braces 21 and 22 is a ridgedflat bar 27, attached to a pin 28a, pin 28a is attached to each side ofthe front braces 21 and 22, in holes 29a, FIG. 2 and FIG. 3, the pin 28aacts as a hinge and lets bar 27 swing up and down, bar 27 is as wide asthe space between the front braces 21 and 22, narrows down until it isas narrow as the beginning of base 15, and as long as base 15, bar 27has an airfoam pad 30, on the bottom side, directly in line with pad 16,FIG. 1 and FIG. 3. Airfo-am pads are of 2 parts, 16a base and 30:! basehaving higher sides, and foam pad 16b and 30b which have smooth coveringare anchored to base 30a16a, FIG. 13.

Above bar 27 attached to be level with the top of back plate 18, is anidentical bar 31 FIG. 1 and FIG. 3, but is made of clear plastic, doesnot have a pad, is slightly longer than lower bar 27 and base 15, is thesame width from one end to the other as the space between the frontbraces 21 and 22, has an upward curve 32, on the end over pads 16 and 30FIG. 1 and FIG. 3, in the center of bar 31 near the curved end 32 is aprinted round black circle 33, with an X 34, marked in the center ofcircle 33, and short lines 35 following in the center of bar 31 towardsthe hinged area FIGS. 1 and 3.

A rectangular block 36 which 'has 2 pins 37a and 37b in the center, oneopposite of the other FIG. 5 slips through the back of plate 18 throughopening 20, and on between the braces 21 and 22 until even with thefront part, of braces 21 and 22, and the 2 center pins 37a and 37b touchthe back of plate 18 FIG. 3 and FIG. 4, pins 37a and 37b are in ahorizontal position, one on each side of opening 20 in the back of plate18, said pins are anchored to back plate 18 with braces 38a and 38b,braces 38a and 381) are fitted so that pins 37a and 37b are free to turninside of said braces, pins 37a and 37b anchored this way letrectangular block 36 tilt up or down FIG. 4, the other /2 of therectangular block 36 is left protruding in the back of plate 18, FIG. 4.

The hollow tube 39 is fitted through the center of the rectangular block36, FIG. 3, the tube 39 has a flange 40 which fits in groove 41, groovebeing on the inside of the rectangular block 36 FIG. 5, FIG. 6, FIG. 10.The tube 39 fitted in this way cannot slide back and fort-h, but willturn inside of the rectangular block 36, tube 39 extends over base 19 inback of plate 18 and has a round knob 42 at this end FIG. 1, FIG. 3, andFIG. 4, a chalk holder 43, FIG. 7, screws into the other end of tube 39which extends in front of braces 21 and 22. FIG. 1 and FIG. 3, chalkholder 43 extends from this tube 39 to the edge of airfoam pads 16 and30, FIG. 3, chalk holder 43 is cut open lengthwise FIG. 8, the end ofchalk holder 43 which extends to the airfoam pads, 16 and 30, is linedwith airfoam FIG. 8, the other end which screws into 39a has threads 43aand a flange 4311, the threads 43a fit into threads 39a, flange 43bkeeps chalk holder 43 from screwing any further than this flange 43binto threads 39a so as not to shorten chalk holder 43 which must be atthe edge of pads 16 and 30, this same end has a hinge 45 FIGS. 8 and 9,the hinge 45 keeps the 2 pieces of the chalk holder 43 together and letschalk holder open and close FIG. 7 and FIG. 8, the hinge 45 has a pinspring 46 with its loop over pin 47 of binge 45, the 2 ends 48 of spring46 are anchored, one to each half of chalk holder 43 FIG. 9, this spring46 opens chalk holder 43 when said holder is unscrewed from tube 39, apiece of chalk 49 is placed in /2 of chalk holder 43, with part of chalk49 left protruding out, FIG. 7 and FIG. 8, both pieces of chalk holder43 are pressed together, chalk holder 43 is screwed back into hollowtube 39, this keeps chalk holder 43 closed, which causes airfoam lining44 to press against chalk 49' holding chalk 49 firmly to keep it fromslipping, also cushions it to keep it from breaking.

A side plate 49 is fitted in each corner on the outer sides of the frontbraces 21 and 22 FIG. 11A, side plate 49 has 2 prongs 50 and a lowerwedge 49a, with a tension spring 52 out of the way of the prongs 50 FIG.12, prongs 50 of side plate 49 rest in holes 51, holes being in thefront braces 21 and 22, wedge 49a extends in front of braces 21 and 22.To keep side plates 49 in place is a rim 53 on the base 17 area,starting from the back plate 18 around to the front of braces 21 and 22,and rims 25 and 26 FIG. 2, When both side plates 49 are pressed at thesame time, plate 49 pushes prongs 50 through holes 51 and under bars 27and 31, wedges 4911 under tube 39, raising all three at one timeFIG. 11Band FIG. 1when pressure is released on side plates 49, tension spring 52pushes side plates 49 back against rims 53 and rims 25 and 26, FIG. 11a.FIG. 3 shows bars 27 and 31 and chalk holder 43 back in startingposition.

After taking out a few pins out of material and pattern along the areaof the pattern where the marks are to be transferred to the material,using one hand, with fingers on one side of the back plate 18 and thumbon the other side, the side plates are pressed to raise chalk holder andtube 39 and bars 27 and 31. These are raised for easy placement ofmarker and to keep marker from marking while placing in correctlocation. Place marker underneath of double material and pattern, withthe other hand, raise 1 layer of material over chalk marker 43, raisepattern over bar 27, holding marker with side plates 49 still pressedin, place other hand above area tobe marked to steady pattern. With aslight back-and-forth motion, with base of marker on flat surface, pushmarker until marks to be marked are seen in the center of the circle 33of bar 31. The hand on the pattern is moved up and the thumb andforefinger is cupped around bar 31, side of palm is resting on pattern.Fingers and thumb steady marker while side palm of hand steadiespattern, the other hand releases side plates 49 which puts marker inposition for marking, turn knob 42 for marking dots, or marker is heldby back plate 18 only and pulled back to mark lines, the fingers andthumb cupped around bar 31 steady marker but let it slide through thumband forefinger when pulling marker for marking lines.

The weight of bar 27 pushes pad 16 against chalk 49, chalk 49' pushesagainst pad 31 causing equally dividing of material for perfectlymatched markers. If marker is used with a hard base and no pad on thebar 27 top material is raised over the chalk and causes mismatchedmarking Any side of the material may be marked by placing chalk 49' onthe side to be marked. For both sides of double material to be marked atone time, marker is placed between the double material. FIG. 1 showsboth sides marked at one time. FIG. 3 shows top side of material beingmarked. Pattern is always between bar 31 and bar 37. Different colors ofchalk may be used of blackboard type chalk but the chalk is only A indiameter.

General design of individual parts of the invention may be changed inregard to manufacture and production. However, in general it isnecessary to use (1) airfoam pads for perfectly matched marks, (2) anairfoam lined, cut lengthwise and hinged chalk holder with thin chalkand airloam lining for the purpose of holding chalk firmly and tocushion against breakage, (3) a weight bar pushing material againstchalk or chalk against material, (4) a line-up bar, to see dots andlines of the pattern through the top of the bar, (5) side plates toraise chalk marker holder and both bars at the same time.
